In “Blue and Red Can’t Make Purple” by Abigail Schneider, the relationship between the brother and sister starts off on good terms. They both understand each other very well, like they are the same person. The main character often finds himself drifting away from reality and getting distracted, but the sister, Eri, knows him very well. She helps him throughout all of his problems. Because of these actions, he describes her as “the cement block that keeps my head attached”. Although as they get older, Eri falls into the negative factors of society and slips from her brother’s grasp. He describes how she changed, and is scared that they may not have the same understanding they had before. Growing up, this does happen to most siblings. As a kid, my brother, sister, and I were inseparable. We did everything together, but then we began to get our own friends, and go different places. We are still a huge part of each other, but the bond we shared isn’t as strong.
